How can you carry a toolbox and a workspace on the luggage carrier of a bike? That’s the question Berto Aussems was confronted with when he sought to take his work as an electronics repairer on the road. In the past he kept a toolbox in the trunk of his car, but then he came up with a more environmentally friendly solution – a DIY mobile toolbox and workbench that folds up to fit on a bike rack! The portable workbench is able to transport all the tools needed for light repairs using only a bike, and the toolbox top folds out with the help of a piano hinge and a few brackets. The workbench is removable from the bike rack and is able to stand on its own (stowable) legs made of aluminum tubes. Even though the portable workbench only weighs about 10kg, it’s able to support Aussem’s body weight. It’s a wonderful addition to any maker’s bicycle and a great solution to work on projects in the field. You can find a complete, step-by-step, project plan over at Instructables.
